[Solved] Can't get MPD to work with PulseAudio

Question

After a long time using straight Alsa I've been setting up Pulse because I want to send my laptop's audio to a networked device. So far I have audio output working (through my laptop) with everything except MPD.  MPD won't output audio with Pulse enabled; songs stay in "paused" mode.  I run MPD as my local user and have been trying to get this suggested systemd service to work, but it fails when I start it:
systemd[1]: Starting Music Player Daemon (running as 0112358)...

You're suggesting running mpd as its own user?  If I did that, and configured mpd to output to 127.0.0.1, etc, would Pulse then be able to redirect the audio to another networked machine (since that's my end goal here)?  I don't want to end up having to put the other machine's IP directly in mpd.conf, since I won't always be running that way (since it's a laptop - sometimes I'll take it on the road and use headphones).
Pulse can do that, yes, its very flexible that way. Doesn't matter where the audio comes from, really. Though as a disclaimer, I haven't tried it myself yet.
Why not just set two outputs for mpd and toggle between them since it has native support? Doesn't sound like you really need pulseaudio.
